ANTHONY PLANTON, DEOEASED, BY GUSTAVUS PLANTON, ADMINISTRATOR, OF

PHILADELPHIA, PENNSYLVANIA.

CONSTRUCTION OF RAILROAD-CARS.

Specification of Letters Patent No. 218, ldated June 3, 1837.

To all 'whom t may concern Be it known that I, GUs'rAvUs PLAN'roN, ofPhiladelphia, in the State of Pennsyl- Vania, son and administrator ofthe late ANTHONY PLAN'roN, a. naturalizedl citizen of the United States,wishing to secure in trust for the heirs-at-law of the said AN- THONYPLANToN the advantages to be derived from the railroad-car invented byhim, do hereby declare that the following is the full and exactdescription of the same.

The nature of the invention consists in constructing the car without theaxl'etrees at present in use, and in giving to each wheel, by meansofits standard, the power of a lateral action, enabling thereby the carto be moved in a circle the diameter. o-f which is extremely small, infact, no greater7 or even less, than its own length; for by the rotarypower existing in the perpendicular pivot-standard, hereafter to bedescribed, it can be made, not only to travel in a straight line, but tofollow the sinuosit-ies of any curved line without altering materiallyits speed. VIn this mode of construct-ion, the running off the track,the lateral friction and the dangers arising from the breaking ofaxletrees, all of which defects of the present plan, are entirelyprevented.

To enable others skilled in the art to make and use this invention, Iwill proceed to describe its construction and operation.

Construct the body of the car after any of the known forms, and adapt toits under surface four strong circular plates of iron, (see Figure 1stin the annexed drawing, E,) in the center of each of which there is aperforation for the admission of a stoutV so as to allow between themthe performance of a rotary action, with antifriction rollers (D D). Theneck of the pivot (B) ofthe standard is secured by a head in the insideof the car over the upper plate, withf out interfering with itsk powerof rotation, and the lower extremityof vthe standard,

l (A) a short distance from the Vunder surface of its cap, (I) isdivided into two forks or legs, (A A) for the insertion of the wheel,

the periphery of which has a concavity or any other shape t-o correspondto the form4 of the rail.

The figure 2d in the drawing shows another mode` of construction on thesame principle. In this the upper plate (E) has the pivot fixed into it,so that the.` rotary cast separately with a square hole in the a centerto receive the square part of the pivot (H) see Fig. 1st.

What I claim as my fathers invention,

and desire to secure by Lett-ers Patent, is-` l. The substitution forthe axletrees now in use, of four upright pivot standards, (as abovedescribed) which contain the wheels and possess the power of rotation.

2. I also claim their mode of construction, and their application to anyform of car or locomotive, that may be used on railroads. Y

' Administrator.
